A brief history of Mortal Kombat's innovations and improvements coincides with the release of the Mortal Kombat Arcade Kollection, which bundles together three of the series's first few games as an Xbox 360 and PlayStation 3 download.

There's also a much longer video on the same subject that forms one of the regular MKast episodes, with chat from creator Ed Boon and many other series veterans.

"Each Mortal Kombat game was more intense in terms of everything," recalls Boon. "The size of the team went from 4 people to 6 people for Mortal Kombat II, and then maybe 8 for Mortal Kombat 3."

"Now there's over a hundred people on the team and it's gone from this garage band production to almost a movie production because of the scope of what we're doing."
